PASTE- APPLYING DEVICE.

SPECIFICATION forming part of Letters Patent No. 681,101, dated August 20, 1901.

Application filed April 16, 1901.

Be it known that L-PATEIOK F. OAssmY, of Boston, in the county of Sufiolk and State of Massachusetts,have invented certain new and usefullmprovements in Paste-Applying Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to paste-applying devices.

The objects of the invention are to provide simple and eflicient means for holding the viate the tendency of clogging the mechanism by the collection of hard dry paste, and to enable the holder to be easily replenished.

The invention will be hereinafter fully set claims.

In the accompanying drawings, Figure 1 is a view in perspective, parts being broken away. Fig. 2 is a view of the paste-reservoir tion on line y y, Fig. 3. tary view.

Referring to the drawings, 1 designates a Fig. 5 is a fragmenerably of rubber, formed with transverse corrugations 3. In the bed near one end is a transverse cut-out or chamber i'of length nearly equal to the width of the bed.

The pasting device 5 comprises a cylindrical reservoir,preferably of metal,havin g an opening 6 in its top. The ends of the reservoir are formed with depending ears 8, in which is journaled the paste distributing nal slot 10 in the bottom. This slot is sufficiently wide to. permit the roller to revolve and carry upon its surface a thin film of the adhesive fluid.

so that the paste will in the revolution of the roller be directed away from the. ends and toward the center of the reservoir.

The distributing-roller is formed at each end with corrugations 13, designed in the application of paste to engage the transverse corrugations of the mat, and thereby efiect the turning of the roller, while fine encircling threads 14, formed on the roller throughout its length, insure the collection of a sufficient quantity of the paste in the passage of the roller through the reservoir. The cover is of slightly less normal diameter than the reservoir over which it clamps, covering nearly all of the latter except at the bottom, where its edges are bent downwardly into vertical portions 16, paralleling the roller and forming guards to prevent the operators fingers contacting therewith. These vertical portions engage the bed on opposite sides of the roller-chamber, forming stops which prevent the roller from contacting with the bottom of such chamber. When thus positioned, the roller engages wire projections 17, which hold it as against lateral displacement, and hence out of contact with the sides of the chamber. A short lug 18 in the top of the reservoir engaging a recess 18 in the cover prevents axial turning of the latter.

In the use of paste-applying devices which employ adistributing-roller difficulty is frequently experienced from the fact that the roller does not turn, owing to the collection of hard dry paste around its bearings, render ing the proper distribution of the paste impossible, but by my invention this difficulty is obviated. The operator holds the pasteapplying device by grasping the reservoir, andthe sheet of paper or card to which the paste is to be applied is laid upon bed 1. Only slight pressure is needed to distribute the paste, since the engagement of corrugations 13 and 3 effects the rotation of the roller.

In addition to the advantage above set forth it will be noted that the cover for the paste-reservoir renders the latter practically air-tight and that when the device is not in use the roller fits in the chamber and. is supported by the cover, the ends of which also serve to guard the operators fingers fromcontact with the roller. By providing the reservoir with and roller are moved over the bed, substan-.

tially as set forth.

2. The combination with the bed having transverse grooves on its upper surface, and a chamber near one end, of the paste-holder,

- a roller fitted in an opening in the bottom of bottom, a paste-applying roller fitted in said such holder and designed to rest in said chamber when not in use, means for holding said roller out of contact with the walls of said chamber when located therein, and means on said roller for coacting with the grooves-of said bed when the paste-holder is moved over the latter, substantially as set forth.

3. The combination with the bed having transverse grooves on its upper surface and a chamber near one end, of the paste-holder,

a roller fitted in an opening in the bottom of such holder and designed to rest in said chain her when not in use, stops carried by said holder for engaging said bed and holding the roller out of contact with the walls of the, chamber when located therein, and means on said roller for coacting with the grooves of the bed when the paste-holder is moved over the latter, substantially as set forth.

4. In a paste-applying device, a horizontally-disposed cylindrical reservoir formed with a longitudinal charging-opening in its j top and a corresponding outlet-opening in its outlet-opening, a metallic cover of substantially the sameshape as, but of slightly less normal cross-sectional area than, the reservoir on which it is designed to clamp, and means for locking the cover as against lateral displacement, as set forth.

5. In a paste-applying device, a horizontally-disposed cylindrical reservoir formed with a longitudinal charging-opening in its top and a copresponding outlet-opening in its bottom, a paste-applying roller fitted in said outlet-opening, a metallic cover of substantiallythe same shape as, but of slightly less normal cross-sectional area than, the reser-' voir over which it is'designed to clamp, said cover having depending portions extend ing below the reservoir and paralleling said roller, and means for locking the cover as against lateral displacement, substantially as set forth.

6. In a paste-applying, device, a reservoir, a paste applying roller below the bottom thereof, and guards on each side of and paralleling said roller, as set forth.

7. In a paste-applying device a reservoir, a paste -applying roller below the bottom thereof, and a cover for said reservoir having vertical portions projecting below the bottom of said reservoir and held away from the roller to form parallel guards on opposite sides thereof, as set forth.

8. In a paste-applying device, a cylindrical reservoir having a charging-opening, a pasteapplying roller below the bottom of such res- 1 ervoir, a cover conforming to, but of slightly less normal cross-sectional area than, said reservoir having depending vertical portions extending below said reservoir paralleling said roller on opposite sides thereof to form guards therefor, as set forth.

9. In a paste-applying device, a paste-res ervoir having an openingin its top and a longitudinal slot in its bottom, ears depending from said reservoir, a pasteedistributing' roller journaled in said ears and designed to project into said paste-reservoir through said slot, and a cover for said opening clam-ping said reservoir and having vertical portions extending below the reservoir and paralleling said roller on opposite sides thereof, as set forth.

10. In a paste-applying device, a reservoir having an opening in its bottom, a paste-ap plying roller fitted in said opening, and deflectors in said reservoir near the ends thereof set at an angle to such ends, as and for the purpose set forth. 7
